Lola loves the hide a squirrel puzzle! I sit with her and keep stuffing the squirrels back in, it lasts awhile because she is very gentle with it and I only let her have it once in awhile, she also LOVES her everlasting treat ball,
Amazon.com: Everlasting Treat Ball - Large: Kitchen & Housewares
she just chews on it forever and the treats are pretty in expensive to replace, come in different flavors and last a long time, I have heard of dogs being able to pop the treats out but Lola never has, I actually need a screw driver to pry them in. She loves this toy, she carries it to her bed and sleeps with it everynight
